Non consensual? Then it can be called rape.
I mean, if the guy is incapacitated, doesn't want oral sex (maybe she's ugly? Maybe he's in a relationship or gay?) from this woman, then I reckon rape is a fair call. The question of non-consent might seem a tough one (bearing in mind, of course, that arousal is an instinctual response rather than explicit consent to a sexual act), but the same issue applies for females anyways; if a woman is drunk or drugged, and wakes up to find someone shagging her, then surely we wouldn't question her right to declare that as being rape?
